ORGANIZED BUNCH-BUILDING MECHANISM FOR SPINNING O8 EW'ISTING 3 Application filed September 9, 1922. Serial No. 587,0;1.

To all whom it may concern: 7

Be it known that we, JAMns H. HooK, JOHN P. THoMPsoN, and MILO E. Woonnow, citizens of the United States, residing at Corsicana, in the county of Navarro and State of Texas, have invented new and useful Improvements in Organized Bunch- Building Mechanism for Spinning or Twisting Frames, of which the following is a specification.

he object of our said joint invention is the provision of a simple, durable and re liable bunch building mechanism desi ed more especially to build bunches on ing bo bins for automatic looms and to operate in combination with a filling feeler with a View to assisting the feel-er in reliable oper-' ation-i. e., in avertingall of the yarn being unwound from the bobbins before the fee-ler br' 5 about changing of the bobbins in the s uttles and at the same time to limit the amount of yarn left on the bobbins when the change takes place, thereby avoiding the formation of thin places in cloth which would naturally be the result were all the yarn unwound from the bobbins.

o the attainment of the foregoing the inventionwhich is also advantageous because it reduces waste to a minimum, consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, part of this specification igure 1 is a front view of an organized forming Bimechanism constituting one embodiment of our invention. 7 V

Figure 2 is a detail broken elevation taken at right angles to and projected fromFigure 1.

I Figure 3 is a detail vertical section taken in the plane indicated b, the line 33 of Figure 1, looking tower the right.

igure 4 is a front view of a modified organized mechanism constructed in accord ance with our invention.

Figure 5 is a side view of said modified mechanism.

Similar numerals designate corresponding parts in Figures 1 to 3 to which reference will first be made. H

Carried by the frame 1, an end of which is shown in F igure 2, are brackets 2, and journaled in the said brackets 2 is a rock shaft 3 on which is a lateral arm 4, disosed below a bracket arm 5 on the frame 1.

terposed between the said shaft arm 4 and ingly maintain the shaft 3 in and return the same to the position shown in Figures 1 and v 2. F ixed to the shaft 3 wardly therefrom is a erably, thou h not necessarily, ovided at 8 with an 0 set portion. Also ted to and extending upwardly from the shaft 3 is a clutch lever 9 associated as shown in Figures 1 and 2 with a circumferentially grooved disk 10. The said disk 10 is mounted on a shaft 11, which is connected in the ordinal or any other approved manner with and is adapted to operam the traverse of the rin rail of the apparatus. iseommon to spinning frames and 'we have therefore deemed it unnecessary to illustrate the same. Fast on the shaft 11 is a cam 12, and arranged between the disk 10 and the cam 12 1s a second cam 13. The cam 12 is retained on the shaft by a nut 14 or other appropriate means. The cam 13 is rotated through the medium of studs 15 which are fast to said cam 13 and extend through a. ertures 16 in the cam 12. When the cam is moved through the medium of the lever 7 into a position close to the cam 12;, said cam 13 is in such, osition that it will engage the roller on t e builder bar. When said cam 13 is in its normal ino erative position shown by dotted lines in igure 2 it does not engage the roller on the builder bar.

At 17 is an arm on the spindle rail of the apparatus, and at 18 is a lateral sub-lever connected at 19 to the lever 7. Interposed between and connected to the arm 17 the sub-lever 18 is a retractile spring 20. At 21 is an arm attached to theframe of the apparatus, and at 22 is a trip member of lever type, fulcrumed at 23 on thejsub lever 18 and having a lateral portion 24 opposed to the lower end of a rectilinearly movable rod 25.

At 30 is a sub-frame fixed in any a proved manner to the frame 1. .Thenod 7 5 is guided in the upper and lower barsl lr and 32 of said sub-frame, and agpring 3 3 which surrounds the rod 25 between an ahiitment 34 on the th 'ggppsr bar 31 of the sub-frame. Jr; W noticed by reference to Figure 1 that i e rod 25 is provided with a series of bevele id teeth 3 5.; the series of teeth being employed so that the size ofthe bunch can be regulated; Movable rectilinearly in the sub-frame 31 at and extending uplever 7 which is prefright angles to the line of movement of the rod 25 and adapted to engage the teeth of the rod 25 are upper and lower, spaced catches 40 and 41. The said catches 40 and 41 are pressed forwardly by springs 42 and their forward ends are opposed to the perimeters'icf the cams 12 and 13.

In the general operation of the mechanism described when the frame is stopped for dofling purposes an attendant grasping the knob 60 on the rod 25 pulls the said rod upwardly and moves the lever 7 forwardly until the sub-frame or catch 18 engages with i the arm or kee er 21. The movement of the lever 7 and t e attendant rocking of the shaft 3 forces the cam 13 against the cam 12, whereupon both cams will act against the roller of the builder arm 61 and thus 'bring about a short stroke or traverse of rin rail and will cause a short bunch to be ma e at the bottom of each bobbin. As before indicated the size of the bunches is regulated by the number of notches employed in the rod 25.

The release of the cam 13 is effected when the oint of the cam 12 contacts with the catc 40. At the said time the catch is forced out of the notch in the rod 25 whereupon the rod will be forced downwardly by the spring 33 and into engagement with the catch 41. The rod 25 then engages the lever 22 which disengages the lever 18 from the keeper 21. The cam 13 is forced backwardly by the action of the spring 6 so that the cam 12 only will be engaged with the roller on the builder arm. This assures full and regular strokes or traverse of ring rail, and the mechanism is not further manipulated until the'frame is read to dofl' again.

It will be gat cred from the foregoing that bobbins on which bunches are built by our improvement are especially designed for use in feeler looms; also, that our novel methanism is simple and compact in construction and embodies no delicate parts such as are likely to get out of order after a short eriod of use.

In t e modification shown in Figures 4 'I and 5, cams 12 and 13 on a shaft 11 are employed;the cams and shafts being similar to the cams 12 and 13 and the shaft 11 of the embodiment shown in Figures 1-3. In

common with the mechanism of Figures 13,

the modified construction also comprises a rock shaft 3, a circumferentiallygrooved disk 10, a lever 9 and a body 10' and a spring 6.

In the modification and in combination with the elements enumerated we employ a trip 22*" and trip lever 22",]a builder arm 60 carrying an anti-friction roller opposed to the earns 12- and 13*; a pick gear 7 O and a let-ojfl' pawl 71, the pick gear, let-off pawl and trip lever beingdesigned to serve the same purpose as the rod 25 of Figures 1-3 and the appurtenances thereof. In accordance with usual practice the pick gear is attached to the builder arm 60, and said pick gear is moved vertically by the cams acting against the roller on the builder arm. Mamfestly as the pick gear moves upwardly the let-oil pawl 71 retains its position as one of its ends is heavier than the other. The end of said pawl 71' remote from the weighted end is equipped with a let-off dog 71* which engages the teeth of the pick gear. Therefore, incident to downward movement of the builder arm, the pick gear is turned through a part of a revolution, or step by step until a pin on the pick gear engages the trip lever and discngages the loose cam 13 from the cam 12 whereupon said cam 13 will be out of alinement with the roller on the builder arm and the worm cam 12 will control the movement of the builder arm until the frame is ready to dofi again. In the modified construction the bunch size is re lated by the positioning of the pin 70 in t e pick gear; said pick gear being provided as shown with a lurality of apertures in any one of which t e pin can be laced as conditions require.

e also show in Figures 4 and 5, a runoff gear 80, the usual shaft 81 carrying the let-off pawl and the worm 82 meshed with the gear 80 and the usual builder chain 83 connected with the gear 80 and passed about a sheave 84, mounted upon the builder or spinning frame head 85.

Having described our invention, what we claim and desire to secure by Letters-Patent, 1s:--
